Power is not the same as efficiency

26 February 2021 Twenty-seven GC-amenable pesticides and their isomers regulated in the cannabis industry in North America stand out as challenging to analyze using liquid chromatography-triple quadrupole mass spectrometry (TQ LC/MS) with electrospray ionization (ESI). In this application note, Agilent Technologies outlines a complete workflow that achieves required limits of detection (LOD), limits of quantitation (LOQ), accuracy, and precision defined by the California Bureau of Cannabis Cont...

16 February 2021 Elemental analysis with traditional EDS (energy dispersive X-ray spectroscopy) runs on a dedicated hardware and software system. This requires constant switching between two separate operating platforms, usually navigating through complex workflows to get to the answer. In this application note, discover how the Thermo Scientific™ ColorSEM™ Technology can overcome this, delivering new levels of speed, convenience, and insight during SEM EDS analysis.

1 February 2021 Pandemics present a unique civic challenge for public health officials. How do you monitor infection levels in large groups of people who are very close together in a repeatable way, using limited labor and reagents? The answer lies beneath our feet. Sewers carry the viral components shed by infected individuals to wastewater treatment plants, where those components settle with solid waste into an unsavory but informative component: sludge.

In this application note, MembraPure GmbH explains the presence of amino acids in beer utilizing the amino acid analyzer ARACUS. 

The stakes are high in biologics development, especially in host cell protein (HCP) analysis. Get it wrong and it could delay your development cycle. See how optimizing your HCP assays can smooth your route to market.

27 January 2021 Circulating tumor cells (CTC) are rare cells shed from a solid tumor or metastases that circulate through the bloodstream. Detection of CTC poses a challenge because they are present at extremely low concentrations, as few as a couple CTC in several milliliters of blood, which contain up to 3 to 6 million cells per mL. To determine the sensitivity and accuracy of rare cell detection on the Agilent NovoCyte Quanteon flow cytometer, a tumor cell spiking assay was used in which a s...

The global epidemic caused by SARS-CoV-2 virus has raised a need for serological testing to detect SARS-CoV-2 specific antibodies. Serological testing can be used as a convenient tool e.g. in epidemiological studies to understand and monitor the progression of epidemic in populations. For the vaccine development serological testing can be used in clinical trials to monitor vaccine response and IgG formation over time. After vaccination programs have been implemented, serological sur
